Long COVID-19 Fatigue & Obstructive Sleep Apnea

Status Recruiting

Clinical Trial Summary

Identify the relationship of obstructive sleep apnea (OSA) prevalence with post-COVID-19 fatigue that remains at least six months after acute disease

Clinical Trial Description

The presence of fatigue symptoms up to 6-7 months after acute COVID-19 disease, similar to myalgic encephalomyelitis/chronic fatigue syndrome, also observed after other viral infections, have been reported as the most frequent post-COVID-19 symptom (Townsend et al., 2020). There is a physiological plausibility for OSA being a causal factor to COVID-19 morbidity and fatigue symptoms by nocturnal hypoxemia, exacerbating or causing endothelial dysfunction, inflammation, oxidative stress, microaspiration and cardiac dysfunction. OSA activates the renin-angiotensin-aldosterone system (RAAS) and angiotensin-converting enzyme-2 (ACE2), which is the SARS-CoV-2 entry receptor in the cells (Miller et al., 2021). In this study we will identify the prevalence of OSA and it's relation with post-COVID-19 fatigue that remains for at least six month after the acute disease, in patients that attend the post-COVID-19 Out Patients Hospital Clinics. It will be studied also the relation between fatigue and vaccination status, nocturnal hypoxemia, day time sleepness and the acute COVID-19 severity. Data collection will be performed by a questionnaire administered by qualified clinical study staff (i.e., by physicians who conduct the post-COVID-19 medical consultation). Demographic, clinical data and clinical research forms will be collected between 6-7th month after the diagnosis of COVID-19 (t1) and 9 months later (t2). Fatigue will be assessed using the Chalder fatigue scale - CFQ-11 (Chalter et al., 1993). The evaluation of OSA related daytime sleepiness will be measured using the Epworth Sleepiness Scale - ESS (Johns, 1991). The OSA diagnosis will be performed using portable monitoring device type III (in-home polygraphy), between 6-7th month after the diagnosis of COVID-19 (t1). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
